Thomas,
Genesys has a calendar hierarchy associated with it. In the hierarchy, rotating patterns are higher than preferences so you can only do one or the other but not both. If you want to do agent preferences, you would have to unassign the staff from the rotating patterns unless you go in and grant all of the preferences.
Calendar Object Hierarchy
When you enter more than one kind of Calendar item for an agent at the same time, a hierarchy determines which takes precedence. The higher priority item appears as Granted, and incompatible lower-priority items appear as Declined.
The order of priority for exceptions and preferences is:
1.Granted full-day exceptions.
2.Granted days off.
3.Granted full-day time off.
4.Granted availability.
5.Granted shifts.
6.Granted paid (working) hours.
7.Granted part-day exceptions, granted part-day time off.
8.Rotating patterns.
9.Preferred items (including exceptions, paid hours, and time off with preferred status).
